PATENT SERVING APPARATUS FOR DINING-ROOMS.

SPECIFICATION forming part of Letters Patent No. 659,0 datedoetobe!1900- Applieation filed December 15, 1898. Serial No. 699,400. (Nomodel.)

To all whom it may cor (Learn:

Be it known that I, JAMES DOYLE, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inServing Apparatus for Dining-Rooms, of which the following is aspecification, reference being bad therein to the accompanying drawings.

Myinvention relates to certain new and useful improvements in servingapparatus for dining-rooms.

One object of my invention is to construct an apparatus of thischaracter for serving a guest in the dining-room by dispensing with theusual waiters.

A further object of my invention is to provide means by which a guestcan indicate the food desired to a chef, and which consists of asuitable indicator arranged in the kitchen and connected to thedining-table and which is operated by a series of push-buttons arrangedin the dining-table.

A further object of my invention lies in my improved carrier for servingthe food desired, which has been ordered by the guest by means of theindicator.

My invention finally consists in the novel combination and arrangementof parts to be hereinafter more fully described, and specificallypointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate corresponding parts throughout theseveral Views, in which Figure 1 is a vertical longitudinal sectionaview of my improved apparatus. Fig. 2is a perspective view of one of thebrackets for supporting the track and dumb-waiter. Fig. 3 is a top planview of my improved diningtable, showing the same connected to anannunciator. Fig. 4 is a side elevation, partly in section, ofmyimproved dumb-Waiter. Fig. 5 illustrates a perspective view in fulland dotted lines, showing the end of the dumbwaiter sections arranged inthe securing-collar. Fig. 6 illustrates a top plan view of thedumb-waiter, showing in dotted and full lines the clamp for securing thesections of the dumb-waiter together. Fig. 7 isa perspective View,partly broken away, of the collar to which are secured thecarrying-sections of the dumb-waiter. Fig. 8 is a perspective view ofthe dumb-waiter, showing the carrying-section in position.

Referring to the drawings by reference-numerals, 1 indicates thedining-room; 2, the kitchen; 3, the dining-table, connected to theannunciator 4 by means of the wires 5; 6, the dum b-waiter; 7 ,the trackfor thedumb-waiter 8, the supporting-brackets for the track and endlesscable 9, and 10 the cord or cable for lowering the track anddumb-waiter.

Referring to Fig. 2 of the drawings, which illustrates one of myimproved supportingbrackets and a portion of the track, and in which 1212 indicate a pair of elongated hollow casings, each provided in itsouter side with the elongated slot 13. These casings 12 12 are supportedat one end thereof by the adjustable bracket 14, provided at its lowerend with the outwardly-extending supports 15 upon which the ends of thecasings 12 12 are mounted. 16 indicates the supportingbracket for theadjustable bracket and within which the bracket 14 is elevated andlowered. The bracket 16 is provided at its top with theoutwardly-extending flanges 17 to receive a suitable fastening means forsecuring the bracket to the ceiling of a room. The bracket 16 is furtherprovided on each. side thereof with a series of guides 18, each havingan opening arranged therein through which operates the supporting andguide pin 19 for the casings 12 12. The lower end of this pin is securedto the casings, as at 20. The top of the bracket 16 has arranged thereinan opening, and above the same is secured a pair of keepers 21, to whichis connected a pulleywheel 22. The cord or cable 10 operates over thesaid pulley through the opening in the bracket 16 and is connected tothe bracket 14 for elevating or lowering the same. The hanger-arm of thedumb-waiter, to be herein described, is secured to the yoke shapedhanger 24, which is supported from the easings 12 12 by means of theshort shafts 25, each provided with the antifriction-roller 26. Theserollers are mounted in the casings 12 12, as shown. The upper face ofthe hanger 24 is provided with an offset 27, which is engaged by thelugs 28, mounted on the continuous operating cord or cable 9, which isconnected to a suitable power means. (Not shown.)

My improved dumb-waiter consists of the hanger-arm-29, suitably securedto the yokeshaped hanger 24. This hanger-arm 29 is provided in its lowerend with a recess 30, adapted to receive the supporting-rod 31, to whichthe carrying-sections 32 of the dumbwaiter are connected by means of thecollar 33 and the clamps 34. The upper end of the rod 31 is retainedwithin therecess by. means of the spring-catch 35, having its lower endbent to form a hook 36, which operates through an opening in the arm 29and engages in an annular groove 3'7, formedin the rod 31, near theupper end thereof. The catch 35 is pivotally secured; to the keepers 38,mounted on the periphery of'thearm 29, and has the spring 39, pressingagainst the same in the manner shown for retaining the hook in position.The lower end of the rod 31 is provided with a head 40 for supporting-This collar 33 has arranged the collar 33. therein a series of V-shapedcut-away portions 41 and a centrally-arranged recess 42; The clamps 34are pivotally connected to the solid part of the collar, as at 34, andoperate within V-shaped portions, as shown, and engage the inner end 43of each carrying-section 32, which are each provided with asubstantially V-shaped inner end of the same size as the cut-awayportions and have suitably arranged therein a groove 44, in whichengagesthe clamp, and by this means the sections are secured to the collarThese sections are substantially quadrant shape, as shown.

The top 45 of my improved dining-table 3 is divided into the sections46, 47, 48, and 49, and which are provided with a series of pushbuttons49, each button having a suitable number arranged above the same. Thebuttons are countersunk within the top 45 of the table and connected bysuitable wires 5 to an annunciator 4, arranged in the kitchen.

ticles therein are correspondingly numberedwith the push-buttons andwhich coincide with the numbers and disks of the annunciator. Forexample, the disks of the indicator are provided with such inscriptionsas Roast beet, Roast turkey, &c., each disk corresponding with thenumber upon the bill'of' fare and upon the table, so that all that theguest does is to push the proper button, and

attached to the hanger-arm 29, the cable 9 is started, and the lug 28,engagingthe ofiset 27, carries the yoke-shaped hanger and do mbwaiterwith the cable until the proper. table is reached, when the trackanddumb-waiter are lowered by means of the cord or cable 10 and theguest served either by removingthe order from the dumb-Waiter or byremoving the section 32 andthe order carried thereby.

It is thought thatthe many advantages of my improvedconstruction can bereadily understood from the foregoing description,

taken'in connection with the accompanying drawings, and it will be notedthat various changesmay be made in the details of construction withoutdeparting from the. general spirit of my invention.

Having thus fully described my invention, what I'claim as new, anddesire to secure by Letters Patent, is-

1. In combination, a track, a dumb-waiter adjustably supported from saidtrack with its receiving-platform comprising a series of removablesections, means for securing said sections together, and means formovingsaid dumb-waiter along the track to the desired position.
